I buy a printer for $125 and ink cartridges cost $15 each. Explain the relationship between the cost of ink cartridges and the total cost.
Answer:
125+15c=t
Step-by-step explanation:
Every cartridge is worth $15, so that would be 15c aka 15 x however many cartridges you purchase. Then the printer is $125, and its not changing so there will be no variable. Put those two amounts together and you'll get the total cost. (Hopefully I explained this well enough.)
Could someone help me with 19 please :)

The value of g(-4) for the given function g(x)=x+4 is 0.
What are piecewise functions?Piecewise functions are functions that have multiple pieces, or sections. They are defined piece by piece, with various functions defining each interval. Piecewise functions can be split into as many pieces as necessary. Each piece behaves differently based on the input function for that interval. Pieces may be single points, lines, or curves.
For −5 ≤ x ≤ −1
Lets take all range of values of x
g(-5) = x + 4 = -5 + 4 = -1
g(-4) = x + 4 = -4 + 4 = 0
g(-3) = x + 4 = -3 + 4 = 1
g(-2) = x + 4 = -2 + 4 = 2
g(-1) = x + 4 = -1 + 4 = 3
For −1 < x ≤ 5
Lets take all range of values of x
g(0) = 2 - x = 2 - 0 = 2
g(1) = 2 - x= 2 - 1 = 1
g(2) = 2 - x= 2 - 2 = 0
g(3) = 2 - x= 2 - 3 = -1
g(4) = 2 - x= 2 - 4 = -2
g(5) = 2 - x= 2 - 5 = -3
Therefore, the value of g(-4) for the given function g(x)=x+4 is 0.

What is 3/5 written as a percent?
A. 6%
B. 30%
C. 60%
D. 167%
Answer:
60%
Step-by-step explanation:
1/5 equals 20 % and thus 3/5 is 20 % multiplied by 3 so 60 %
Answer: "Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as
x/100
.
We can then rewrite this as: 60%.

Jordan Ellen recycle cans Jordan recycle seven cans for every 12 cans Ellen recycled last week how many total cans did Jordan and Ellis recycle last week.
Answer:
Ellen sold 42 cans and they sold 114 cans lastweek (both Ellen and Jordan)
Step-by-step explanation:
The oroginal ratio is 7:12 for every 12 cans ellen collects Jordan collects 7 so inorder to find the number of cans Ellen sold you have to figure out what 7 was multiplied by to get 42, and that would be 6. Then you multiply 12 by 6 and get 72 so ELlen sold 72 cans.
Now the new ratio is 42:72 when you add them together you get 114 so they sold (together) 114 cans last week.

y = -4x - 12
What is the slope(m) and the y-intercept (b)
Answer:
x=6.0
Step-by-step explanation:
the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12,
In the equation y = -4x - 12, the coefficient of x, -4, represents the slope of the line. The slope (m) is the ratio of the vertical change to the horizontal change between any two points on the line. In this case, the slope is -4, indicating that for every unit increase in x, the y-value decreases by 4.
The constant term, -12, represents the y-intercept (b). The y-intercept is the point where the line intersects the y-axis. In this equation, the y-intercept is -12, which means that the line crosses the y-axis at the point (0, -12).
To summarize, the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12, representing the point where the line crosses the y-axis.

The number of cells in an embryo as it develops in the womb is modeled in the form [tex]f(x) = 2^{kt}[/tex] , where T is the time in months. If the fetus is estimated to have 32 cells in the first month, how many cells does a newborn have on average?
Answer:
2^45 or ≈ 3.5*10^13Step-by-step explanation:
Given equation
f(t) = 2^(kt)f - number of cells, t - number of months, k- coefficientWe got 32 cells in the first month. It means:
t = 1, f(1) = 32Using these numbers we can find the coefficient k:
32 = 2^(k*1) 2^5 = 2^kk = 5Then the equation becomes:
f(t) = 2^(5t)Average time is 9 months, we can calculate the number of cells:
f(9) = 2^(5*9) = 2^45 ≈ 3.5*10^13Due Wed 10/21/2020 11:30 po

w = 4
L = 7
Step-by-step explanation:
L = length of rectangle
w = width of rectangle
L = 3 + w
A = 28
A = L*w
=(3+w) * w
28 = 3w + w^2
w^2 + 3w - 28 = 0
w^2 + 7w - 4w - 28 = 0
w ( w + 7 ) - 4 ( w + 7 ) =0
( w - 4 ) ( w + 7 ) = 0
w = 4. and w = -7
take the postive value, w = 4
therefore L= 3+4 = 7
